java http 的一点小问题

CoolEgos 2014-04-27 10:09:38
首先写了一个servlet
package com.zf.login;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class LoginServlet extends HttpServlet {

/**
* Constructor of the object.
*/
public LoginServlet() {
super();
}

/**
* Destruction of the servlet. <br>
*/
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}

/**
* The doGet method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to get.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

String username = request.getParameter("username"); //得到username
String password = request.getParameter("password"); //得到password
System.out.println("username = "+username);
System.out.println("password = "+password);
response.setContentType("text/html");
response.setContentType("utf-8");
PrintWriter out = response.getWriter();
/*
out
.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
out.println("<HTML>");
out.println(" <HEAD><TITLE>A Servlet</TITLE></HEAD>");
out.println(" <BODY>");
out.print(" This is ");
out.print(this.getClass());
out.println(", using the GET method");
out.println(" </BODY>");
out.println("</HTML>");
out.flush();
out.close();
*/
}

/**
* The doPost method of the servlet. <br>
*
* This method is called when a form has its tag value method equals to post.
*
* @param request the request send by the client to the server
* @param response the response send by the server to the client
* @throws ServletException if an error occurred
* @throws IOException if an error occurred
*/
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

String username = request.getParameter("username"); //得到username
String password = request.getParameter("password"); //得到password
System.out.println("username = "+username);
System.out.println("password = "+password);
response.setContentType("text/html");
response.setContentType("utf-8");
PrintWriter out = response.getWriter();

/*
out
.println("<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">");
out.println("<HTML>");
out.println(" <HEAD><TITLE>A Servlet</TITLE></HEAD>");
out.println(" <BODY>");
out.print(" This is ");
out.print(this.getClass());
out.println(", using the POST method");
out.println(" </BODY>");
out.println("</HTML>");
out.flush();
out.close();
*/
}

/**
* Initialization of the servlet. <br>
*
* @throws ServletException if an error occurs
*/
public void init() throws ServletException {
// Put your code here
}

}


然后协议一个测试http的代码:
import javax.net.ssl.HttpsURLConnection;
import java.net.URL;
import java.io.InputStream;
public class TestHttp
{
public static void main(String[] args)
{

try{
new Thread(){
String startUrl="http://192.168.1.106:8080/loginTest/servlet/LoginServlet?username=ddd&password=dddd"; //记录路径
URL url = new URL(startUrl);
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
}.start();
}
catch(Exception e){
e.printStackTrace();
System.out.println("连接失败啊!!!");
}
}
}


我直接在浏览器进入的时候servlet端会有东西打印出来,而运行测试的时候显示连不上是怎么回事啊?

你connection 要关闭。 你 url 打开后做什么处理了。 你这个 e.printStackTrace(); 错误信息是什么。

刚才的测试代码 有点问题
import java.net.HttpURLConnection;
import java.net.URL;
import java.io.InputStream;
public class TestHttp 
{
	public static void main(String[] args) 
	{
		
		try{
			new Thread(){
				String startUrl="http://192.168.1.106:8080/loginTest/servlet/LoginServlet?username=ddd&password=dddd";   //记录路径
				URL url = new URL(startUrl);
				HttpURLConnection conn = (HttpURLConnection)url.openConnection();
			}.start();
		}
		catch(Exception e){
			e.printStackTrace();
			System.out.println("连接失败啊!!!");
		}
	}
}
是HttpURLConnection 而不是HttpsURLConnection 大拿还是没有结果显示啊??
